TOOL FOR CEMENT-WORK.

Specification of Letters Patent.

Application fil d December 19,1906. Serial No. 348,647,

To all whom it may concern:

Be it known that I, RALPH L. SOHN, a citizen of the United States, residing at Arrowsmith, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Tool for Cement-Work and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in tools for cement work, particularly for smoothing, edging, and marking the surface of cement and similar plastic work.

It has for its object to provide a convenient means for attaching the handles to edgers, creasers, or markers, trowels, floaters, and any other tools of this class, whereby said handles may be adjusted at different angles without disconnecting said handles.

The invention consists of the features of .construction and combinations of parts hereview of the nut, and Fig. 5 is a plan view of a plastering-trowel with my handle attachment secured thereto.

Referring more particularly to Figs. 1 to 4 of the drawings, 1 designates a creaser or marker, such as is usually employed in laying concrete sidewalks, &c. On the upper surface of said creaser or marker a platform 2 is formed, the upper surface of which is cupped slightly, as shown in Fig. 2. Cast in the creaser and projecting from the platform is a screw-threaded lug or bolt 3.

The handle attachment 4 comprises a flat plat e-like portion 5 and an upstanding portion 6 at one end of said flat portion. Said upstanding portion is slotted at 7 to receive the handle 8, which is secured by a bolt 9; The fiat portion 5 of said handle attachment is also slotted at 10 to fit the screw-thread bolt 3, and the upper surface thereof has a circular groove 11 therein. The under surface is cupped slightly for the same reason as the platform 2namely, for better holding "the handle attachment.

The bolt 3 is fitted with a nut 12, provided on its bottom surface with a ring-flange 13 to fit the groove 1 1. By means of this arrangement the nut may be loosened a little to permit the angle of the handle attachment to be changed without letting said handle attachment slide out of position or become disengaged from the tool.

In Fig. 5 I have illustrated my invention as it may be applied to a plasterers trowel. In this figure, 14 is the trowel, and 15 is the platform, which is made in a separate piece with extending arms 16, riveted to the body of the trowel. The bolt 3 is cast in the flat form, and the handle attachment is secured in place in the same manner as above described;

I claim- 1. The combination, with a tool of the character described having a projecting screw-threaded bolt, of a handle attachment having a slotted portion to fit said bolt and provided with a circular groove in its upper surface, and a nut having a ring-flange adapt Edge fit in said groove for the purpose specie 2. The combination, with a tool of the, character described having a raised platform provided with a projecting screw-threaded bolt, of a handle attachment having a slotted portion to fit said bolt and provided with a circular groove in its upper surface, and a nut "having a ring-flange adapted to fit in said groove for the purpose specified.

3. The combination, with a tool of the character described having a raised platform riveted thereto and provided with a projecting screw-threaded bolt, of a handle attachment having a slotted portion to fit said bolt and provided with a circular groove in its upper surface, and a nut having a ring-flange adapted to fit in said groove for the purpose specified.

4. The combination, with a tool of the character described having a raised platform provided with a projecting screw-threaded bolt, of a handle attachment having a slotted portion to fit said bolt and provided with a circular groove in its upper surface, the surface of said platform and the under surface of said slotted portion of said handle attach- Inent being cupped, and a nut having a ring- With a handle, and a nut having a ring-flange flange adapted to fit in said groove for the adaptedto fit in said groove for the purpose purpose specified. specified.
